I asked yesterday about saving a timer value when the browser closes and then start counting again when the user opens it. I’ve found that using cookies must be a good solution, so i’ve added the set and getcookie functions, but still i can’t get my timer values. This might be easy, but i cant see what’s wrong because i’m still too noob in javascript.
Does someone know what i’m doing wrong?
thank you!!
here’s the code i have so far:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head>
    <title>Test</title>
    <script type="text/javascript">
var sec = 0;
var min =  0;
var hr = 0;
var dias = 0;
var bool = true;
function stopwatch() {
        sec++;
        if (sec == 60) {
            sec = 0;
            min += 1;
        }

        if (min == 60) {
            min = 0;
            hr += 1;
        }

        if (hr == 24) {
            hr = 0;
            dias += 1;
        }

        totalTime = ((dias<=9) ? "0" + dias : dias) + "d, " + ((hr<=9) ? "0" + hr : hr) + " : " + ((min<=9) ? "0" + min : min) + " : " + ((sec<=9) ? "0" + sec : sec);
        document.getElementById("timer").innerHTML = totalTime;
        if (bool == true) {
        start = setTimeout("stopwatch()", 1000);

        }
    }

function setCookie(name, value, expires) {
document.cookie = name + "=" + escape(value) + "; path=/" + ((expires == null) ? "" : "; expires=" + expires.toGMTString());
}



function getCookie (name) {
    var cname = name + "=";               
    var dc = document.cookie;

    if (dc.length > 0) {              
        begin = dc.indexOf(cname);       
            if (begin != -1) {           
            begin += cname.length;       
            end = dc.indexOf(";", begin);
                if (end == -1) end = dc.length;
                return unescape(dc.substring(begin, end));
            } 
        }
    return null;
}


var exp = new Date();                                  
exp.setTime(exp.getTime() + (1000 * 60 * 60 * 24 * 30));

    </script>
</head>
<body onload="stopwatch()">
    <div id="timer" name="timer"> </div>
  <button onclick="bool = false"; > pause </button>
  <button onclick="bool = true;stopwatch();" > resume </button>

    <form>
      <input type="button" value="Set a Cookie" onClick="setCookie('myCookie',timer.value, exp)">
    </form>
<form>
<input type="button" value="Get Cookie Value" onClick="this.form.tf.value = getCookie('myCookie')">
<input type="text" name="tf" size="30">
</form>

 </body>
</html>

    Firstly, few issues with your code:

    • Strings shouldn’t be used in setTimeouts
    • Your variables should be initialised as integers, not strings.

    Back to your problem, use the unload event to save a cookie with the current time when the user closes the page. Then when the user opens the page again, detect the cookie and continue from where you left off.
